IMPROVEMENT IN PAPER BOXES.

Specification forming part of Letters Patent No. 217.939, dated July 29,1879; application filed February 4, 1879.

To all whom it may concern:

Be it known that I, LORENZO O. GRANGER, of Newark, in the county ofLicking and State of Ohio, have invented certain new and usefulImprovements in Paper Boxes; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

This invention relates to paper boxes or receptacles formed from blanksby folding, intended for the use of retail grocers, butterdealers,confectioners, &c.

It consists in shaping different forms of such receptacles from uncutblanks of paper or pasteboard in such manner that the surplus ofmaterial shall be folded in the form of plaits on the interior of two ofthe sides or ends of the receptacle, and that the thus plaited endsshall have flaps folded down over the plaits on the inside for thetwofold purpose of connecting the sides to the ends at the top and ofstiffening the ends, so as to provide for a strong attachment of a bailor handle.

In the accompanying drawings, Figure 1 is a perspective view of aflaring-shaped box or bucket, also showing the top or cover ready to beapplied. Fig. 2 is a plan of the blank for forming the flaring style ofbox. Fig. 3 is a perspective view of a straight-sided box. Fig. 4 is aplan of the blank for forming the straight-sided box. Fig. 5 is aperspective of a partly-completed box of the flaring form.

The same letters of reference indicate like parts in all the figures.

For perspicuity of description I shall, throughout this specification,designate the parts of the box on which the lapping folds are made theends thereof.

The dotted lines in the drawings indicate the creases in the blanks.

The blanks for either straight-sided or flaring boxes are cut in theform of rectangles. The blank shown in Fig. A is creased for astraight-sided box, such as shown in Fig. 3.

It is creased lengthwise along the lines A A and crosswise along thelines 13 B.

rection that they will, at the edge of the blank, form junctions withthe creases G O.

Branching outwardly from the junctions of the creases O A O A and O A OA,andfrom the junctions of the creases O D O D and O D G D, are creasesE, running to the respect ive ends of the blank, as clearly shown in thediagram, Fig. 4.

In shaping a straight-sided box from a blank creased as described, onemay proceed as follows The blank is first tucked inward on, say, theright-hand crease D, so as to make the creases A B meet, whereby thetriangular plait d is laid against the inner side of the end 0 of thebox. The blank is folded in like manner upon the right-hand crease D,and the triangular plait d laid over the plait d, as seen in Fig. 5.

The other end of the blank being similarly folded on the left-handcreases D and D shapes the blank into a partly-finished box'withupwardly-projecting flaps e on the ends. These flaps are first foldedinwardly at the outer corners on the creases E, and then folded inwardlyupon the ends of the box along the creases O and C, respectively. Theforming of the box being thus completed, the flaps e and triangularplaits d d are permanently secured to their respective ends 0 of thebox, preferably by means of eyelets, as shown, although they may besecured by pasting or otherwise. The eyelets are preferred because theyafford a convenient means for attaching a wire bail or a tape handle tothe box, should such a device be desired, and the box s made very firmat the points of fastening, where the greatest stress would come shoulda handle be used.

A lid or cover may be made in the same manner as the box proper.

-tudinal creases A A In constructing a box flaring toward the top, ablank creased as shown in Fig. 2 is used, differing from that alreadydescribed in the ibllowing respects: Neither the longinor the transversecreases B B are parallel throughout their entire length, but spreadapart from each other from the corners of the bottom a toward the edgesof the blank. Between the creases A A and the respective edges of theblank nearest thereto the creases O and G approach each other more orless, according to the configuration that is to be given to the box.These creases are therefore only parallel with the creases B B at thatportion of their length which comes between the creases A A. Additionalcreases F are provided, which run from the respective ends of thecreases B and B to the ends of the blank, crossing the creases C O atthe point where said creases cross the creases D D, as shown. In thediagram of this blank, Fig. 2, I have omitted the creases E at thecorners of the blank, for the reason that it depends upon the form of aflaring box whether any folds at all occur at the corners, and whenfolds result at the corners they vary with the varying forms of theboxes.

It is not necessary to form the creases E preliminary to the shaping ofeither the flaring or straight-sided form of box, for it is about aseasy to fold the corners of the flap symmetrically without theassistance of these preliminary creases as with the aid thereof.

It is not required that the corners of the flaps should be folded informing the square boxes, as the flaps can be folded inside the boxwithout such folding of the corners, nor need the corners of the flapsbe folded in the flaring style of box, for the surplus may be bent backso as to lie againstthe sides of the box.

As the plaits d d are folded inside the box, it is obvious that somemeans must be provided to hold them firmly to the ends thereof at thecorners; otherwise the sides could be pulled away from said ends. Thisneeded provision for connecting the sides and ends at the top is made bythe flaps e, which fold down upon the corner plaits, and are firmlysecured to the ends of the box, as already stated.

The blanks may be creased by rolls or any other well-known means, and,for convenience of packing, be furnished to consumers in that form; orthe boxes may be furnished in a completed state.

What I claim as my invention,and desire to secure by Letters Patent, is-

1. A paper box formed from an uncut blank, substantially as before setforth, in which the plaits at the corners are folded inwardly againstthe inner sides of the ends, and the said ends are provided withfull-width flaps for folding down upon said plaits.

2. An uncut blank for a paper box, substantially as before set forth,provided with the described preliminary creases, whereby on folding inaccordance with said creases the ends of the box will have full-widthprojecting flaps.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

LORENZO O. GRANGER.
